It therefore remains unresolved which regions mediate the influence of object identity on action observation.
Further work will be required to determine the identity and mode of action of the causative variant (or variants) at this locus.
Many more genes were grouped into the previously defined temporal categories, confirming the identity and mode of action of meiosis transcriptional regulators.
The gene product(s) must also be characterized for identity, structure, mode of action, specificity, toxicity, and allergenicity (Cockburn, 2001; Codex Alimentarius Commission, 2009; EFSA, 2008a; König et al., 2004).
Key gaps include the identity and mechanism of action of the toxin(s), the incomplete description of effects of exposure in invertebrates, fish, and humans, and the nature and extent of exposures that place people at risk.
Although studies in cell culture indicate that this control might include negative mechanisms [17 19], little is known about the identity and mode of action of specific molecules that inhibit muscle differentiation in vivo during development.
The precise identity and mode of action of the functional variant tagged by rs6465657 is at present unknown, but It is reasonably easy to postulate that the 'C' allele at rs6465657 could be marking a loss-of-function variant with effects on LMTK2 half-life or function.
But he won't accept what has been the inevitable course of an action hero's role -- of identity though action -- if it means killing children or destroying a family.
Despite the unknowns in the identity and action of the cr-associated gene in generating the crest, one thing is certain about it: it is a "gene of large effect".
In addition, while some morphological traits may have relatively simple and common genetic architecture across populations (e.g., Colosimo et al. 2004), cases of multifarious morphological distinction that we have described will almost surely be considerably more complex in the number, identity, and action of genes that control such variation.
